Original application filed May 25, 1911, Serial No. 629,269.

Specification of Letters Patent.

1912- Serial No. 685.080.

To all whom it may concern:

Be it known that I, VILLIMI Sonar, a citizen of the United States, and a resident of Racine, county of Racine, and State of Nisconsin, have invented certain new and useful Improvements in Gang-Flows, of which the following is a full, clear,'and exact description.

The invention relates to gang plows and more particularly to means for adjustably connecting the plows to the draft frame.

The invention seeks to provide simple and effective connecting or coupling devices for connecting the plows to the draft frame and by which the plows may be adjusted in lateral direction and also adjusted to tilt the plow bodies.

The present application is a division of an earlier application filed by me on May 25th, 1911, Serial No. 629,269, in which the entire construction of the gang plow is shown and described.

The present inventio-n relates, as stated, to a coupling means for connecting the plows to the draft frame and consists in the features of improvement hereinafter set forth, illustrated in the preferred form in the accompanying drawings and more particularly pointed ont in the appended claims.

In the drawings, Figure 1 isa plan View showing a portion of the draft frame with two of the plows connected thereto and with parts of the frame shown in section to illustrate the details of the coupling. 2 and 3 are detail sections on the lines Q--Q and 3 3, respectively, of Figs. 1 and 4. Fig. t is a cross-section on the line 4-4f of Fig'. 1.

As set forth in the prior application re ferred to, the wheel supported draft frame preferably comprises a series of longitudinally extending bars 1 connected at their rear ends by a number of transverse angle bars 2, which form a series of steps to which the plows are connected. Only the two rear* most step angle bars are shown in the drawings and one of these bars is in section in le: 1, to show the construction of the coupling. As illustrated, the step angle bars 2 are connected to the longitudinaly bars 1 by angle pieces 3 and the rearmost angle bar 2 is connected to the adjacent longitudinal bar by a brace 4. The several angle bars which form the steps to which the plows are coupled are also preferably connected by an inclined brace bar 5 which extends over the step angles and is secured to the upper horizontal flange of each step bar by a bolt 6.

lnhebeam of each plow comprises two mam bars 7 and 8 which are spaced apart at their rear ends and somewhat further apart at their forward ends. ln the construction shown, the bar 8 is offset intermediate its ends and a filler block 9 is interposed between and bolted to the bars at the inclined offset portion of the bar 8.

The plow bodies 10 may be connected to the beam bars in any suitable manner. In the construction shown, the plow bodies 10 are connected to upwardly and forwardly eX- I tending standards 11 which are arranged be tween the rear portions of the beam bars 7 and 8 and are pivotally connected thereto by bolts 1Q. The ends of each bolt 1Q extend through a pair of brackets 13 which are also secured to the outer faces of the beam bars 7 and S by a bolt 14. The rear portions of the brackets 13 are spaced from the main beam bars 7 and 8 and overlap the forward ends of a pair of supplemental beam bars 15. The latter are connected to the main beam bars at their forward ends by the pivot; bolt 12. At their rear ends, the supplemental beam bars 15 support a block 1G which is connected to the plow standard by a vertical bolt 17. Any other suitable means may be employed for connecting the plow bodies to the beam bars. a

Each of the plow beams is provided with a gage wheel 18imounted on the lower end of a standard 19, the horizontal pivot Q0 of which extends through the brackets 13 below the plow beam. The lift mechanism (not shown) is connected to the gage wheel standard. Other means may be employed for raising and lowering the plows. The parts thus .far described may be of any usual or suitable construction. j

Each of the plows is individually connected to the draft frame and each coupling comprises a substantially horizontal pivot bolt, arranged transversely to the line of draft and upon which the plow swings in vertical direction. Means are provided for adjusting' the horizontal pivot bolt in a veritical plane to tilt the beam bars and plow body connected thereto and means are also provided for swinging the pivot bolt in a horizontal plane to adjust the plow laterally, so that the different plows of the gang may be properly and uniformly spaced from one another.

ln the preferred embodiment of the invention illustrated, a transverse pivot bolt 20 extends through the forward ends of the pair of beam bars 7 and S and through a sleeve 2l interposed between the beam bars. rlhe sleeve 21 has a swinging or ball and socket connection with the frame at one end. As shown, the sleeve is provided with a forwardly and laterally `projecting arm 22 terminating` in a semi-spherical head or ball 23. This ball is seated within a socket formed in a cast metal member 24e which is arranged within the angle of the step bar 2 and abuts against the vertical and horizontal flanges thereof. A lpair of eye-bolts 25 and 26 engage the ends of the pivot bolt 20 outside of the beam bars 7 and 8, extend forwardly therefrom, and pass loosely through openings in the `vertical flange of the step bar 2. The left-hand eye-bolt 25 extends through openings formed in the ball and socket members l23 and 24, and a nut 27, threaded on the forward end of the bolt, engages the front face of the step bar. This bolt holds the ball and socket members in engagement and, in the position shown, with the fiat upper face of the socketmember 24 engaging the horizon- I tal liange of the step bar, so that the socket member cannot turn. lf desired, the socket member may be also bolted or fastened to the horizontal flange of the angle bar.

The eyebolt 26 extends through the righthand portion of the angle bar 2 which projects beyond the end of the adjacent longitudinal frame bar 1. This bolt also extends through one of the strengthening clips or angle pieces 3. Set nuts 28 threaded on opposite sides of the vertical flange of the angle bar 2, serve to adjust the bolt 26 to swing the right-hand end of the pivot bolt 2() horizontally in the direction of the line of draft. The beam bars and plow body connected to the bolt 20 are thus shifted or adjusted in lateral direction and by means of this adjustment,the plows of the gang may be properly and uniformly spaced.

An eye-bolt 29 engages the rear end of the eye-bolt 2G and extends upwardly and vertically through the horizontal flange of the angle bar 2. At its upper end, the bolt is provided with an adjusting nut 30 which rests upon the upper face of the bar 2. rhe lower portion of the nut 30 is cylindrical and is provided with an annular rib or shoulder 31 and these parts of the nut are rotatably mounted within a recess formed in a clip 32. The clip is secured to the upper face of the step bar to thereby hold the nut 30, bolt 29 and the parts connected thereto against vertical movement.

In the form shown, this clip is provided with a hooked the bolt 29 is adjusted in vertical direction and the rear end of the bolt 26 and the right-hand end of the pivot bolt 2O are raised and lowered. ln this way the pivot bolt 20 is swung in a vertical plane and the beam bars and plow body connected thereto correspondingly shifted to level or adjust the plow so that it will properly perform its work.

In effecting the horizontal and vertical adjustment of the pivot bolt 20, it is understood that the nuts 27 and 28 on the horizontal eye-bolts 25 and 26 are irst loosened and when the desired adjustment is effected, these nuts are tightened to securely hold the pivot bolt 20 and pair of beam bars 7 and 8 connected thereto in position, the bolt 2G fits loosely in the opening in the parts 2 and 3 so that the rear end of the bolt is free to swing .vertically to a limited extent, when the nuts 28 are loosened, suliicient to permit of the desired Vertical adjustment of the pivot bolt 2O about a horizontal axis. ltv is, if course, understood that the pair of beam bars and plow bottom connected thereto are free to swing vertically upon the pivot bolt 20, but they are rigidly held against movement in lateral direction or about an axis extending in the direction of the line of draft.

lt is obvious that changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims.

I claim as my invention 1. ln a plow, the combination with a draft frame, of a trailing plow and a connection between said plow and said frame comprising a. substantially horizontal pivot transverse to the line of draft, adjustable means for swinging said pivot in vertical direcl tion and means adjustable in the direction of the line of draft for swinging said pivot horizontally.
